Abstract
The utility model discloses a highly explosion-proof lithium battery case. The lithium battery case comprises a casing, wherein a casing cover is assembled at the upper part of the casing in a sealing manner; through-holes for mounting a positive terminal post and a negative terminal post are respectively formed on the left side and the right side of the casing cover; an explosion-proof hole for mounting an explosion-proof valve is formed in the middle of the casing cover; the explosion-proof valve consists of an explosion-proof membrane, an explosion-proof needle and a hollow pressing stud; the hollow pressing stud is fixedly connected to the interior of the explosion-proof hole; the explosion-proof membrane is arranged at the lower end of the hollow pressing stud; the explosion-proof needle is fixed in the hollow pressing stud; and the needle head points to the explosion-proof membrane. In the utility model, the needle-type explosion-proof valve is adopted to replace a common spring-type explosion-proof valve, failures of the explosion-proof valve due to corrosion can be well prevented; and the highly explosion-proof lithium battery case has a better explosion-proof effect and a simple structure, and can accurately solve the problem that explosion is caused when a battery is misused or in other accidental situations.
Description
Technical field
The utility model relates to a kind of shell of battery, particularly a kind of high explosion-proof li battery shell.
Background technology
Lithium battery is widely used in accumulation power supply systems such as waterpower, firepower, wind-force and solar power station, the uninterrupted power supply of post and telecommunications, and a plurality of fields such as electric tool, electric bicycle, battery-operated motor cycle, electric automobile, military equipment, Aero-Space.
The high capacity lithium ion battery of exploitation has begun to try out in electric automobile at present, and expectation will become one of major impetus power supply of 21 century electric automobile, and will be applied aspect artificial satellite, Aero-Space and the energy storage.Along with the pressure of the in short supply and global environmental protection aspect of world energy sources, the lithium electricity just is being widely used in the electric motor car industry, and the particularly appearance of LiFePO 4 material battery has more promoted the development and the application of lithium battery industry.
But general lithium battery poor stability is blasted easily.To the problems referred to above, in the present high capacity cell plastic housing explosion-proof technology, be mainly the spring explosion-proof valve; Explosion-proof elastic force is difficult to reach accurate unanimity, and spring receives the influence of electrolyte and peripheral environment air plankton, overwhelming majority meeting generation corrosion; Its elastic performance is by influence greatly; Be difficult to reach desirable explosion-proof effect, or owing to too tightly lose explosion-proof meaning, or too pine causes leakage to cause battery to scrap.
The utility model content
In order to overcome the deficiency of prior art, the utility model provides a kind of security performance high and li battery shell attractive in appearance.
The utility model solves the technical scheme that its technical problem adopted:
A kind of high explosion-proof li battery shell; Comprise housing; Said housing top seal is equipped with cap; The left and right sides of cap is respectively arranged with the through hole of mounting anode and cathode post, is provided with the explosionproof hole that explosion-proof valve is installed in the middle of the cap, and it is characterized in that: said explosion-proof valve is made up of rupture pressure disc, explosion-proof pin and hollow pressure spiral shell; Said hollow pressure spiral shell is fixedly connected in the explosionproof hole, and said rupture pressure disc is arranged on the lower end of said hollow pressure spiral shell, and it is inner that said explosion-proof pin is fixed on hollow pressure spiral shell, and syringe needle points to rupture pressure disc.
As the improvement of technique scheme, be distributed with the round boss that matrix form is arranged on four sides of said housing.
As the further improvement of technique scheme, said hollow pressure spiral shell is provided with external screw thread, is fixedly connected with explosionproof hole through external screw thread.
Further, it is inner that said explosion-proof pin is welded on hollow pressure spiral shell.
Further, it is concordant with the cap surface that said explosion-proof valve is installed the back.
The beneficial effect of the utility model is: the utility model replaces common spring explosion-proof valve through adopting the pin type explosion-proof valve; The explosion-proof valve that can better avoid causing owing to corrosion lost efficacy; And explosion-proof performance is better; Simple in structure, can solve the prominent abuse of meeting of battery accurately and wait the fortuitous event problem of the sudden and violent secure context that rises of generation down.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the profile of vertical plane of symmetry of the utility model;
Fig. 3 is the partial enlarged drawing of Fig. 2;
Fig. 4 is the vertical view of Fig. 2.
Embodiment
With reference to Fig. 1 ~ 4; A kind of high explosion-proof li battery shell; Comprise housing 1, said housing 1 top seal is equipped with cap 2, and the left and right sides of cap 2 is respectively arranged with the through hole 21 of mounting anode and cathode post; Be provided with the explosionproof hole 22 that explosion-proof valve 3 is installed in the middle of the cap 2, said explosion-proof valve 3 is made up of rupture pressure disc 31, explosion-proof pin 32 and hollow pressure spiral shell 33; Said hollow pressure spiral shell 33 is fixedly connected in the explosionproof hole 22, and said rupture pressure disc 31 is arranged on the lower end of said hollow pressure spiral shell 33, and said explosion-proof pin 32 is welded on hollow pressure spiral shell 33 inside, and syringe needle points to rupture pressure disc 31.Said housing 1 adds 5% ~ 15% glass fiber by white polypropylene to be processed, and can reach ideal flexible, has prevented housing because softness and easy deformation can effectively prevent the battery seepage too.
For strengthening the heat radiation and the aesthetic of battery, be distributed with the round boss 11 that matrix form is arranged on 1 four sides of said housing.Round boss 11 also can play and prevent that extraneous power from directly touching housing, plays the effect of protection battery simultaneously.
As the preferred implementation of the utility model, said hollow pressure spiral shell 33 is provided with external screw thread, is fixedly connected with explosionproof hole 22 through external screw thread.Further, it is inner that said explosion-proof pin is welded on hollow pressure spiral shell.
For preventing that it is concordant with cap 2 surfaces that said explosion-proof valve 3 is installed the back because of operating the explosion-proof valve 3 of damaging because of carelessness in the battery installation process.
Certainly, the utility model is not limited to above-mentioned execution mode, as long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection range of the utility model.
